The nif’al participle, like the perfect, begins with the נ prefix. Masculine singular perfects and participles are easily confused: the only difference is that with most roots the second syllable of the participle has a kamatz instead of a patakh: נִזְכָּר. In ל”ה roots, the masculine singular perfect and feminine singular participle are identical: נִבְנָה. In general, the final syllables of nif’al participles follow the same patterns as pa’al participles: נִזְכֶּ֫רֶת, נִזְכָּרִים, נִזְכָּרוֹת. gender and number, but not by person.
